  • Publication number: 20210305329
    Abstract: The present disclosure provides a display panel including a plurality of pixel units. Each of the pixel units includes a substrate; a first electrode layer; a light emitting layer; a second electrode layer; and a color shift compensation layer located between the first electrode layer and the second electrode layer and on a light emitting side of the light emitting layer. The color shift compensation layer is configured to compensate for a color shift of light emitted from the light emitting layer at different viewing angles. One of the first electrode layer and the second electrode layer includes a reflective electrode layer, and the other of the first electrode layer and the second electrode layer is a transflective electrode layer. A display device including such a display panel, and a method for manufacturing such a display panel are also provided.

  • Patent number: 9964683
    Abstract: The present disclosure discloses a light guide plate, a backlight module and a liquid crystal module. The light guide plate includes a plurality of light guide blocks; the light guide blocks are doped with scattering particles. Since the light guide plate includes a plurality of light guide blocks, this can simplify the cutting of the light guide plate and the making of grid points. The light guide blocks are doped with scattering particles, so that most of rays incident upon the light guide blocks are scattered in a preset direction and guided to a middle part and the light-far end of the backlight module to compensate the brightness of the middle part and the light-far end, thus making the brightness of the side light type backlight display uniform.
